Derived from wild Alaskan Salmon, this nutrient-rich 100-percent pure salmon oil provides essential building blocks dogs need for a healthy heart and strong immune system. In addition, it helps relieve dry itchy skin, reduces shedding, makes fur soft and velvety, and helps keep the heart, eyes, and joints healthy. The all-natural supplement contains over 15 beneficial Omega 3, Omega 6, and Arachidonic fatty acids, plus a fresh fish flavor. To use, simply pump the salmon oil onto the dog's food directly from the convenient pump-bottle dispenser. A handy weight chart on the label displays the correct amounts to use.
